Title: Hearing aid
Inventor: HAGGARD MARK PEREGRINE
IPC: H04R25/00
Filed: 1981-12-24
Abstract: The invention relates to a hearing aid with a microphone (3), an amplifier (1, 2, 4 to 8, 10 to 12) and an earpiece (9). To improve the listening quality, the amplifier exhibits two parallel amplifier channels (1, 2) having different gain characteristics (1A, 2A). The characteristic of one amplifier channel (1) rises with frequency over the middle frequency range whereas the characteristic of the other amplifier channel (2) corresponds to an approximately constant gain in the entire frequency range. The two amplifier channels (1, 2) in each case contain a gate circuit (5, 6) which are controlled by means of a control circuit (7), which distinguishes between voiced and unvoiced speech tones, in such a manner that voiced components are processed in one amplifier channel (1) and unvoiced components are processed in the other amplifier channel (2). As a result, a higher gain than in conventional hearing aids can be selected without inconveniences arising during the listening. <IMAGE>

Patent DE-3245526-A1 (DE)
Title: Plant for the clarification of sewage
Inventor: SCHEIBINGER LUDWIG DIPL-ING
IPC: E03F5/14
Filed: 1982-12-09
Abstract: In sewage treatment plants, the water flowing off is in many cases directed into settling basins in which the substances contained in the water settle as far as possible. The water freed of these substances runs off over a waste weir. The settling substances are removed from the basins at required time intervals. In the event of extremely heavy rainfall, the water is directed past the sewage treatment plant directly into the settling basins and then, if the settling basins can likewise no longer receive the water, into the free stretches of water. This leads to excess fertilization of the streams, canals, rivers, etc. In order to avoid this, it is proposed according to the invention to arrange a rainwater discharge basin in front of the sewage treatment plant, with an overflow for the excess water via which the excess water runs through a by-pass to a first settling basin which, apart from the conventional waste weir, has increased overflow safety and a second waste weir which is set to the maximum permissible water level.

Title: Power-assisted steering for vehicles with a modulator valve for forming a reaction pressure
Inventor: ROEHRINGER ARNO
IPC: B62D6/00
Filed: 1982-12-23
Abstract: A power-assisted steering system operates with a control valve, which responds to the steering lock of a manual steering wheel, for the working pressure of a power-steering motor and a modulator valve which operates as a function of at least one parameter, in particular the travel speed. The modulator forms a reaction pressure, depending on the parameters, with reduction of an output pressure which is derived from the working pressure. Only the reaction pressure can be sensed at the manual steering wheel as a pressure-dependent reaction as a result of a reaction pressure surface which is formed on the valve actuating element of the control valve and located in a reaction pressure chamber being acted on because the reaction pressure chamber is connected to a working pressure chamber of the power-steering motor and the working pressure chamber is connected via an associated valve connection of the control valve to a working pressure source and, at the same time, the modulator valve is connected in series with at least one throttle between the working pressure source on the one hand and a pressure means discharge which is essentially relieved of pressure on the other. The two reaction pressure chambers which are connected on the one hand to in each case one working pressure chamber are on the other hand connected to one another by means of a short-circuit pressure connection. In order to avoid quantities of leakage oil being released via the modulator valve at relatively low travel speeds, the short-circuit pressure connection contains the throttle which is connected in series with the modulator valve. The modulator valve is connected into the pressure connection between a reaction pressure chamber and the associated working pressure chamber. At low travel speeds, the modulator valve shuts off the pressure connection.
